Abstract: Изобретение относится к движителям и может быть использовано на морских судах. Магнитогидродинамический программно-управляемый вихревой двигатель для морских микродронов выполнен в виде двух цилиндрических металлических электродов, вложенных друг в друга, с тремя электромагнитами. Электромагниты расположены в форме правильного треугольника. При подаче трехфазных синусоидальных сигналов возникает вращающееся магнитное поле в пространстве между цилиндрическими электродами, в результате чего анионы морской воды будут смещаться в сторону положительного электрода по радиальному направлению, а катионы будут двигаться им навстречу, что приведет под действием силы Лоренца к вихревому вращению в пространстве между цилиндрическими электродами с одновременным выталкиванием их вдоль образующей цилиндрических поверхностей. Программное изменение параметров амплитуд и частоты синусоид позволяет осуществить управление вектором тяги двигателя. Достигается программное управление вектором тяги. 1 ил.
